Analysis of solids densification during the pressurization …

During the gas pressurization phase of the operating cycle, gas pressure gradients add to the solids stresses caused by gravity, resulting in a gain of density and strength of the solid. The increase of strength may require a larger hopper outlet and, hence, a larger valve at the outlet in order to assure flow without obstructions thus increasing the initial cost and the cost and time of ...

Lock Hopper

The lock hopper, or pressure-transfer vessel, is filled from the hopper above. The lock hopper is then pressurized to the same pressure as the blow tank, either by means of a pressure balance from the blow tank, which acts as a vent line for the blow tank while it is being filled, or by means of a direct line from the main air supply.
